Simplified:
struct X
{
X(bool) { }
};
int main()
{
X x{1.2};
}

--- Comment #1 from Jonathan Wakely ---
Clang does now:
narrow.cc:9:9: error: type 'double' cannot be narrowed to 'bool' in initializer
list [-Wc++11-narrowing]
X x{d};
^
narrow.cc:9:9: note: insert an explicit cast to silence this issue
X x{d};
^
static_cast( )
1 error generated.
And EDG gives:
"narrow.cc", line 9: error: invalid narrowing conversion from "double" to
"bool"
X x{d};
^
1 error detected in the compilation of "narrow.cc".
